Answer:
18
Step-by-step explanation:
f(2)=4x+10
f=(4)(2)+10
f=8+10
f=18
Answer:
2
Step-by-step explanation:
The constant of proportionality in the equation x/y = 2/g is 2. 2 is the only number in the equation.
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
